Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The embodiment is as follows:

referring to fig. 1-3, the air leakage prevention basketball comprises a ball body 1 and an inflating valve 2, wherein the inflating valve 2 comprises a pipe body 3, a first fixing pipe 4 is fixed in the middle of the annular inner wall of the pipe body 3, and a conical groove is formed in the bottom of the annular inner wall of the first fixing pipe 4;

a second fixing pipe 5 is fixed at the bottom of the annular inner wall of the pipe body 3, vent holes 6 distributed at equal intervals are formed in the top of the second fixing pipe 5 along the annular shape, and gas can enter the sphere 1 through the vent holes 6 through the arranged vent holes 6;

a connecting rod 7 is inserted and slid in the second fixed pipe 5, a blocking piece 8 is fixed at the bottom end of the connecting rod 7, and when the ball body 1 is filled with air through the arranged blocking piece 8, the blocking piece 8 is extruded by air pressure, so that the blocking piece 8 is tightly attached to the bottom of the second fixed pipe 5 to block the air vent 6;

a conical block 10 is fixed at the top end of the connecting rod 7, the conical groove is matched with the conical block 10, a spring 9 is sleeved on the outer wall of the connecting rod 7 in a sliding manner, the spring 9 is positioned between the second fixing pipe 5 and the conical block 10, and the spring 9 pushes the conical block 10 to be inserted into the first fixing pipe 4 for plugging through the arranged conical block 10;

the top of toper piece 10 is fixed with movable rod 11, and the top of movable rod 11 is fixed with lantern ring 12, and the through-hole that the equidistance distributes is seted up along the annular in the top of lantern ring 12, and the external diameter of lantern ring 12 and the internal diameter looks adaptation of body 3, lantern ring 12 make things convenient for the inflating nozzle to insert the back extrusion, make movable rod 11 and connecting rod 7 remove downwards, make the inflation channel open.

The working principle is as follows:

when the basketball is inflated, the inflation nozzle presses downwards against the top of the lantern ring 12, the movable rod 11 presses the conical block 10 downwards, so that the conical block 10 is separated from the bottom in the first fixed pipe 4, the spring 9 is compressed and contracted at the moment, and the blocking piece 8 is far away from the bottom of the second fixed pipe 5;
